HTML5 Tags Filter - costes - Jul. 24, 2014 02:31 PM
Hello
Would it be possible to create a filter that removes or blocks html5 while using js?. this in order to prevent tracking features such as canvas fingerprinting or the use of the modernizer helper library from js?
https://www.browserleaks.com/canvas
https://www.browserleaks.com/modernizr
A simple solution would be to just disable js in your browser but regulary you need js enabled.
Thank you.

The
prox-config-sidki_2011-12-22rc1 filterset merged with Proxblox have the filters to defeat canvas fingerprinting without disabling javascript. I can't say which filter specifically as mine blocked the test page on the first visit.

Thanks
although is not listed on the filters of proxblox my guess would be to copy a similar filter and replace the <HTML5> header
In = FALSE
Out = TRUE
Key = "! ProxBlox: Enable <HTML5> Removal (Out)"
URL = "(^$TST(a_bypass=*.HTML5.*))$SET(a_html5=1)"
..

I'm no expert, but I had a look at several pages that included methods for fingerprinting browsers, and added |canvas|bin2hex|crc|next.host.loader to the Kill Nosey Javascript filter. That did it. :-) Probably a bit of overkill. :-)
Though I also note that they appear to be using https for some of their stuff.
There's these interesting items that I found:
